# Description

# Root Zone Label Generation Rules for the Devanagari Script

## Overview

This file contains a set of Label Generation Rules (LGR) for the Devanagari script for the Root Zone. For more details on this LGR and additional background on the script, see “Proposal for a Devanagari Script Root Zone Label Generation Rule-Set (LGR)” [Proposal-Devanagari]. This file is one of a set of LGR files that together form an integrated LGR for the DNS Root Zone [RZ-LGR-6]. The format of this file follows [RFC 7940].

## Repertoire

The Root Zone LGR for the Devanagari script lists 83 single code points in addition to 27 sequences, for a total of 110 repertoire entries. The two sequences U+0931 U+094D U+092F ऱ्य and U+0931 U+094D U+0939 ऱ्ह limit the character U+0931 ऱ DEVANAGARI LETTER RRA to its own specific context, beyond which it does not stand by itself. Accordingly, while U+0931 ऱ is not listed by itself, it brings the total of distinct code points to 84.

A number of other sequences have been defined in connection with the definition of variants (see “Variants” below).

The repertoire includes code points used by languages written in Devanagari that fall within levels 1 to 4 on the [EGIDS] scale. Boro, Braj, Dhundari, Mundari, Kharia are additionally covered. Though listed as level 4 on the EGIDS scale, Saraiki is not covered, because the Devanagari script is “no longer in use” by the Saraiki community. A non-exhaustive list of languages using each code point can be found in the comments. For more details, see Section 5, “Repertoire” in [Proposal-Devanagari].

The repertoire is contained in [MSR-6], which is a subset of [Unicode 16.0.0].

As part of the Root Zone, this LGR includes neither decimal digits nor the HYPHEN-MINUS.

Repertoire Listing: Each code point or range is tagged with the script or scripts with which the code point is used and one or more other character categories. For each repertoire element, one or more references document sufficient justification for inclusion in the repertoire; see the “References” below. For code points that are part of the repertoire, comments identify the languages using the code point along with their [EGIDS] level, as well as alternate names of some code points.

Code points outside the Devanagari script repertoire that are listed in this file are targets for out-of-repertoire variants and are identified by a reflexive (identity) variant of type “out-of-repertoire-var”. They do not form part of the repertoire.

## Variants

According to Section 6, “Variants”, in [Proposal-Devanagari], this LGR defines variants based on being “Confusing due to deviation from normally perceived character formations by the larger linguistic community.” These cases are not of mere visual similarity, as they involve some deviations from the widely accepted norms of Devanagari akshar formations. They can cause confusion even to a careful observer and hence have been defined as variants. They fall into three broad categories:

- Vowel/Vowel sign followed by Nukta
- Unique Vowels and Vowel Signs required for Kashmiri
- Variants based on Candrabindu and Candra Vowel Signs followed by Anusvara

In addition to these, cross-script variant analysis of Devanagari identified cross-script variants with the Gurmukhi and Bengali scripts. The analysis additionally found possible cross-script confusables that do not rise to the status of variants. They are listed in Appendix 1 of [Proposal-Devanagari].

Variant Disposition: All variants are of type “blocked”, making labels that differ only by these variants mutually exclusive: whichever label containing either of these variants is chosen earlier would be delegated, while any other equivalent labels should be blocked. There is no preference among these labels.

This LGR does not define allocatable variants.

The specification of variants in the Root Zone LGR follows the guidelines in [RFC 8228].

Context Rules for Variants: Some of the variants defined in this LGR are “effective null variants”, that is, some code points in the source map to “nothing” in the target with all other code points unchanged. (Because mappings are symmetric, it does not matter whether it is the forward or reverse mapping that maps to “null”.) Such variants require a context rule to keep the variant set well behaved.

In other cases, the sequences or code points making up source and target are constrained by explicit context rules on the code points (or by implicit context rules defined for the adjacent code points). In such a case, any variants may require context rules that match the intersection between the effective contexts for both source and target; otherwise, a sequence might be considered valid in some variant label when it would not be valid in an equivalent context in an original label. Symmetry requires the same context rule for both forward and reverse mappings.

The Halant is only a variant at the end of a label, when it does not partake in forming a conjunct.

The Candrabindu has an in-script variant limited to a specific context and an unrestricted cross-script variant.

## Character Classes

Devanagari is an alphasyllabary, and the heart of the writing system is the akshar. This is the unit which is instinctively recognized by users of the script. The writing system of Devanagari could be summed up as composed of Consonants, Halant, Vowels, Anusvara, Candrabindu, Nukta and Visarga.

Consonants: Devanagari consonants all contain an implicit schwa /ə/. To make a full syllable, consonants may be followed by certain code points from one or more of the other groups (see “WLE rules” below). See Section 3.3.1, “The Consonants” of [Proposal-Devanagari].

Halant (aka Virama): Because all consonants contain an implicit vowel schwa /ə/, a special sign is needed to denote that this implicit vowel is stripped off. This sign is the Halant, encoded as U+094D ् DEVANAGARI SIGN VIRAMA. The Halant thus joins two consonants and creates conjuncts, which can be generally from 2 to 4 consonant combinations. In rare cases, it can join up to 5 consonants. However, this LGR will not enforce any length limit. The nominal rendering of the Halant is visible only at the end of the label.

See Section 3.3.2, “The Implicit Vowel Killer: Halant” in [Proposal-Devanagari].

Vowels and Matras: There are separate code points for vowels that are pronounced independently at the beginning of a syllable or after a vowel sound. To indicate a Vowel sound following a consonant other than the implicit schwa sound, a vowel sign (matra) is attached to the consonant. There is an equivalent matra for each vowel excepting U+0905 अ DEVANAGARI VOWEL A. See Section 3.3.3, “Vowels” of [Proposal-Devanagari].

Anusvara: The Anusvara shows a nasal at the end of a syllable. See Section 3.3.4, “The Anusvara” of [Proposal-Devanagari].

Candrabindu: A Candrabindu denotes nasalization of the preceding vowel. Present-day Hindi users tend to replace the Candrabindu by the Anusvara. See Section 3.3.5, “Nasalization: Candrabindu” of [Proposal-Devanagari].

Nukta: The nukta sign is placed below a certain number of consonants to represent sounds found only in words borrowed from Perso-Arabic, English, and other non-Aryan sources. It is also placed under the consonants U+0921 ड and U+0922 ढ to indicate flapped sounds. Apart from this, the Santali language uses Nukta adjoined to certain vowels and vowel signs. See Section 3.3.6, “Nukta” of [Proposal-Devanagari].

Visarga: U+0903 ः DEVANAGARI SIGN VISARGA, representing an aspiration at the end of a syllable, is frequently used in Sanskrit. See Section 3.3.7, “Visarga and Avagraha” of [Proposal-Devanagari].

## Whole Label Evaluation (WLE) and Context Rules

### Default Whole Label Evaluation Rules and Actions

The LGR includes the set of required default WLE rules and actions applicable to the Root Zone and defined in [MSR-6]. They are marked with ⍟. The default prohibition on leading combining marks is equivalent to ensuring that a label only starts with a consonant or vowel. The actions compute a label disposition based on WLE rules or variant mapping types.

### Devanagari-specific Rules

These rules ensure that the Devanagari label conforms to akshar formation norms for the Devanagari script. These norms are exclusively presented as context rules.

The following symbols are used in the names and comments for WLE rules:

- C → Consonant
- M → Matra
- V → Vowel
- B → Anusvara (Bindu)
- D → Candrabindu
- X → Visarga
- H → Halant / Virama
- N → Nukta
- S → Eyelash Reph (C2HC3) where:
  - C2 is U+0931 ऱ DEVANAGARI LETTER RRA
  - H is U+094D ् DEVANAGARI SIGN VIRAMA
  - C3 comprises
    - U+092F य DEVANAGARI LETTER YA
    - U+0939 ह DEVANAGARI LETTER HA

The rules are:

- 1. N: must be preceded only by any of C1, V1 or M1
- 2. H: must be preceded by C or CN
- 3. M: must be preceded by C or CN
- 4. X: must be preceded by any of V, C, N or M
- 5. B: must be preceded by any of V, C, N or M
- 6. D: must be preceded by any of V, C, N or M
- 7. V: Can NOT be preceded by H

The following context rules are used for variants where a Nukta maps to a “null”, or that are overlapped:

- Variant is not defined if followed by a Nukta
- Variant is not defined unless it is followed by V or C (including RRA) or end of label

See Section 7, “Whole Label Evaluation Rules (WLE)” of [Proposal-Devanagari].

The following context rule is used for variants of Halant:

- Variant is not defined unless it is followed by end of label

The following context rule is used for variants of Candrabindu:

- Variant is not defined unless it follows C or CN
- Variant is defined only if it follows C or CN

The last two context rules are complementary. This allows the in-script variant to be limited by context, but the cross script variant to be valid whether or not that context is defined. Because U+0901 ँ has the lowest code point value, it is the index variant.

## Methodology and Contributors

The Root Zone LGR for the Devanagari Script was developed by the Neo-Brahmi Generation Panel (NBGP), the members of which have experience in linguistics and computational linguistics in a wide variety of languages written with Neo-Brahmi scripts. Under the Neo-Brahmi Generation Panel, there are nine scripts belonging to separate Unicode blocks. Each of these scripts has been assigned a separate LGR, with the Neo-Brahmi GP ensuring that the fundamental philosophy behind building each LGR is in sync with all other Brahmi-derived scripts. For further details on methodology and contributors, see Sections 4 and 8 in [Proposal-Devanagari], as well as [RZ-LGR-6-Overview].

### Changes from RZ LGR-3

A clerical error has been corrected in RZ LGR-4: for code points in the V1 and M1 subsets, the character class names “Vowel” and “Matra” were incorrectly not capitalized. This had the effect of disallowing some labels containing an Anusvara, Candrabindu or Visarga together with the affected code points. From RZ LGR-4, these labels are now reported as valid in accordance with [Proposal-Devanagari]. For the prior version see [RZ-LGR-3-Deva].

### Changes from RZ LGR-5

In RZ LGR-6 two missing cross-script variants were added for Candrabindu and Halant and their Bengali counterparts. These code points were mistakenly believed to not participate in the formation of possible variant labels. Context rules are used to ensure that variants do not apply in situations where they should not. For the prior version see [RZ-LGR-5-Deva].

## Repertoire by Code Point

The following table lists the repertoire by code point (or code point sequence). The data in the Script and Name column are extracted from the Unicode character database. Where a comment in the original LGR is equal to the character name, it has been suppressed.

Some code points that may be part of a valid label under this LGR only occur as part of one or more sequences. Such code points are not listed individually in the table.

For any code point or sequence for which a variant is defined, additional information is provided in the Variants column. Some code points or sequences listed in the following table are not part of the repertoire itself; they document targets for out-of-repertoire variant mappings as indicated. See also the legend provided below the table.

Legend

Throughout this document, a code point sequence may be annotated with a string in ALL CAPS that is constructed on the same principle as a name for a Unicode Named Sequence. No claim is made that a sequence thus annotated is in fact a named sequence, nor that the annotation in such case actually corresponds to the formal name of a named sequence.

Code Point
  A code point or code point sequence.
Glyph
  The shape displayed depends on the fonts available to your browser.
Script
  Shows the script property value from the Unicode Character Database. Combining marks may have the value Inherited and code points used with more than one script may have the value Common. Sequences are annotated with a set of all distinct script values.
Name
  Shows the character or sequence name from the Unicode Character Database. Named sequences are listed with their normative names, for ad-hoc sequences the individual names are shown separated by “+”.
Ref
  Links to the references associated with the code point or sequence, if any.
Tags
  LGR-defined tag values. Any tags matching the Unicode script property are suppressed in this view. For sequences, the tags for all member code points are shown in [] for information; sequences as such do not have tags.
Required Context
  Link to a rule defining the required context a code point or sequence must satisfy. If prefixed by “not:” identifies a context that must not occur.
Variants
  Link to the variant set the code point or sequence is a member of, except where a coded point or sequence maps only to itself, in which case the type of that mapping is listed.
Comment
  The comment as given in the XML file. However, if the comment for this row consists only of the code point or sequence name, it is suppressed in this view. By convention, comments starting with “=” denote an alias. If present, the symbol ⍟ marks a default item shared among a set of LGRs.
✔ - core repertoire
  A check mark in the Part-of-repertoire column indicates a code point is part of the core repertoire.
✗ - out-of-repertoire
  A code point shown with ✗ is not part of the repertoire. It is listed only because it is the target of an out-of-repertoire-var variant mapping.

# Variants

## Variant Set Summary

Number of variant sets | 42
Largest variant set | 4
Ordinary Variants by Type |
blocked | 130
Reflexive Variants by Type |
out-of-repertoire-var | 30

## Variant Sets

The following tables list all variant sets defined in this LGR, except for singleton sets. Each table lists all variant mapping pairs of the set; one per row. Mappings are assumed to be symmetric: each row documents both forward (→) and reverse (←) mapping directions. In each table, the mappings are sorted by Source value in ascending code point order; shading is used to group mappings from the same source code point or sequence.

Where the type of both forward and reverse mappings are the same, a single value is given in the Type column; otherwise the types for forward and reverse mappings, as well as comments and references, are listed above one another. For summary counts, both forward and reverse mappings are always counted separately.

A mapping where source and target are the same is reflexive. Variant sets consisting of only a single reflexive mapping are not shown as a set. Instead, the variant type of the mapping is listed in the Variants column of the Repertoire by Code Point table. Reflexive mappings that are part of a larger set are indicated with a “≡” and are counted once per entry.

In any LGR with variant specifications that are well behaved, all members within each variant set are defined as variants of each other; the mappings in each set are symmetric and transitive; and variant sets for each context are disjoint, but code points that have variant mappings with multiple contexts are members of more than one set.

Common Legend

Source
  By convention, the smaller of the two code points in a variant mapping pair.
Target
  By convention, the larger of the two code points in a variant mapping pair.
Glyph
  The shape displayed for source or target depends on the fonts available to your browser.
→ - forward
  Indicates that Type, Ref and Comment apply to the mapping from source to target.
← - reverse
  Indicates that Type, Ref and Comment apply to the reverse mapping from target to source.
↔ - both
  Indicates that Type, Ref and Comment apply to both forward and reverse mapping.
≡ - reflexive
  Indicates that Type, Ref and Comment are for a reflexive mapping where source equals target.
Type
  The type of the variant mapping, including predefined variant types such as “allocatable” and “blocked”; or any that are defined specifically for this LGR. A reflexive variant type “out-of-repertoire-var” designates the target as not part of the repertoire; it is required as target for one or more variant mappings that cross repertoire boundaries. In this LGR, types for variant mappings between out-of-repertoire code points are shown in italic while types for pure in-repertoire variant mappings are shown in bold.
Required Context
  Link to the rule defining a required context the source must satisfy for the variant mapping to be defined. If prefixed by “not:”, identifies a context that must not occur.
Ref
  One or more reference IDs (optional). A “/” separates references for reverse / forward mappings, if different.
Comment
  A descriptive comment (optional). A “/” separates comments for reverse / forward mappings, if different.

Legend

Used as Trigger
  This rule triggers one of the actions listed below.
Used as Context
  This rule defines a required or prohibited context for a code point C or variant V.
Anchor
  This rule has a placeholder for the code point for which it is evaluated.
Regular Expression
  A regular expression equivalent to the rule, shown in a modified notation as noted:
⚓︎ - context anchor
  Placeholder for the actual code point when a context is evaluated. The code point must occur at the position corresponding to the anchor. Rules containing an anchor cannot be used as triggers.
(...)← - look-behind
  If present encloses required context preceding the anchor.
→(..) - look-ahead
  If present encloses required context following the anchor.
( ) - group
  An anonymous nested rule is used to group match operators.
(... | ...) - choice
  When there is more than one alternative in a rule, the choices are separated by the alternation operator (...|...).
start or end
  (start) matches the start of the label; (end) matches the end of the label.
[: :] - named or implicit character set
  Reference to a named character set [:name:] or an implicit character set [:tag:]. A leading “^” before name or tag indicates the set complement.
[\p{ }] - property
  Set of all characters matching a given value for a Unicode property [\p{prop=val}]. Note: uppercase “\P” defines the complement of a property set.
∪, ∩, ∖, ∆ - set operators
  Sets may be combined by set operators (∪ = union, ∩ = intersection, ∖ = difference, ∆ = symmetric difference).
⍟ - default rule
  Rules marked with ⍟ are included by default and may or may not be triggered by any possible label under this LGR.

## Actions

The following table lists the actions that are used to assign dispositions to labels and variant labels based on the specified conditions. The order of actions defines their precedence: the first action triggered by a label is the one defining its disposition.

# | Condition | Rule / Variant Set |  | Disposition | Ref | Comment
--- | --- | --- | --- | --- | --- | ---
1 | if label matches | leading-combining-mark | → | invalid |  | labels with leading combining marks are invalid ⍟
2 | if at least one variant is in | {out-of-repertoire-var} | → | invalid |  | any variant label with a code point out of repertoire is invalid ⍟
3 | if at least one variant is in | {blocked} | → | blocked |  | any variant label containing blocked variants is blocked ⍟
4 | if each variant is in | {allocatable} | → | allocatable |  | variant labels with all variants allocatable are allocatable ⍟
5 | if any label (catch-all) |  | → | valid |  | catch all (default action) ⍟

Legend

{...} - variant type set
  In the “Rule/Variant Set” column, the notation {...} means a set of variant types.
⍟ - default action
  Actions marked with ⍟ are included by default and may or may not be triggered by any possible label under this LGR.

Note: The following variant types are used in one or more actions, but are not defined in this LGR: allocatable. This is not necessarily an error.
